Printing and Scanning


There are Pharos networked printers on each floor of the library. A Princeton netID is required to print from library public computers to these printers. Walk-in users must go to the Firestone Library Access Office for printing privileges. 

A color Pharos networked printer is located on Lewis 1st floor, to the right of the front doors. The cost for color printing is 75¢ per page. You must first set up an account at the Marquand Library in McCormick Hall and ask to speak with a regular staff member (student employees cannot do this for you). You can do this the following days and times: Monday-Thursday from 8:30am-10:00pm, Friday from 8:30am-6:00pm, and Sunday from 2:00pm-10:00pm.. Once money is deposited in this account you will be able to use the color printer. See http://marquand.princeton.edu/printing for more details.
